Participants were placed into groups according to surgical reports (ACL\u2010only, <jats:italic>n<\/jats:italic> = 24; meniscal repair, <jats:italic>n<\/jats:italic> = 12; meniscectomy, <jats:italic>n<\/jats:italic> = 10). Quadriceps strength was quantified using isokinetic and isometric measures. Isokinetic strength was collected at 60\u00b0\/s in concentric mode. Isometric strength was collected at 90\u00b0 of knee flexion. Quadriceps activation was assessed using the burst superimposition technique and quantified via the central activation ratio. One\u2010way ANOVAs were utilized to detect whether differences existed in quadriceps activation and strength between groups.

Though group differences in quadriceps function were not detected, all participants demonstrated levels of quadriceps activation failure that are below healthy individuals at a time when they were returned to sport. Given that persistent quadriceps activation failure is detrimental to knee function, rehabilitation protocols that target quadriceps activation failure should be developed and employed
